To scale down risks, medical examinations are mandatory and overwhelmingly performed using bicycle ergometry, which overlooks some important aspects of diving. Searching ergometric systems that better address the underwater environment, a systematic literature search was conducted using the keywords ‘diving’, ‘fitness’, ‘ergometry’, and ‘exertion’. All presented alternative systems Citation: Dreyer, S.; Schneppendahl, found convincingly describe a greatly reduced underwater physical performance. Thus, if a diver’s J.; Moeller, F.; Koch, A.; Muth, T.; workload in air should already be limited, he/she will suffer early from fatigue, risking a diving Schipke, J.D. An Updated Narrative incident. How to assess fitness? Performance diagnostics in sports is always specific for a modality Review on Ergometric Systems or movement.
